First Claim
Patent Images
1. A monitor for an injection molding machine, comprising:
- sampling means for detecting, at every predetermined cycle, at least the position of a movable member varying in one molding cycle. in an injection molding process and one or more other variables and storing the detected variables; and
means for graphically displaying the variables for a plurality of molding cycles, with a first axis representing the position of said movable member, a second axis representing said other variable and a third axis representing the number of molding cycles.

Abstract
Variables such as injection pressure and injection velocity are detected at a predetermined sampling cycle for each molding cycle and the variables for a plurality of past molding cycles starting from the latest molding cycle are stored. Change patterns of the stored variables of the respective molding cycles are displayed in the form of graphs in which the first axis represents time (the number of times of sampling), the second axis represents the variable values, and the third axis represents the molding cycle.
